The smaller sections contain homemade salsa (heavy on cilantro - So.Good.) and corn chips.
I used a small piece of plastic cling wrap over the section with the salsa and it worked really well to keep it contained. I think as long as you are using a lunchbag that holds the EasyLunchbox flat (such as their own) and you aren't swinging it crazily all around, most liquidy things will stay put very well.

When I read "you aren't swinging it crazily all around most liquidy things will stay put very well", I decided that I want your kids ;) I've watched mine carrying in his lunchbox to school and that's all he does - swing his lunch around, his backpack, narrowly avoiding bopping other kids as he spins around happily. I tried cling wrap over some yogurt once -- lets just say that it didn't go well ;)

Ha! Pigs Do Fly - the thing is, my son has learned the hard way that swinging his lunchbox all over tarnation causes his food to not look so nice when he goes to eat. ;-) So he's pretty careful with it. At least prior to lunch he's careful, after lunch all bets are off. :p

Hi Cranky Apple, thanks! The scraps don't go to waste! For cheese they sometimes get eaten by me or my hovering vultures, um, I mean, darling children. When I can I put them aside for the baby (he's one) since his needs to be cut in tiny nibbles anyway. Sometimes I'll hide the odd pieces under the pretty shapes on top. :)
